Structure of a Ceiling Fan

ABSTRACT

A ceiling fan structure has a motor, a decorative cover, and several blade components. The decorative cover covers on the outer side of the motor and is installed on the motor. Each blade component includes a support and a blade. Each blade is installed on a corresponding support. Each support is installed on the decorative cover. The motor drives the decorative cover to rotate, thereby rotating the blade components.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to a ceiling fan structure and, in particular, to a ceiling fan structure whose blade supports are installed on a decorative cover that is connected to the motor thereof.

2. Related Art

A conventional ceiling fan structure is illustrated in FIG. 3. It has a motor 51. The blades 52 thereof are installed on supports 53, which are then installed on the motor 51. As the motor 51 rotates, the supports 53 are driven to rotate the blades 52. Due to the restriction of suitable position on the motor 51 in such a structure as well as the limited space, the supports 53 and the blades 52 can only be mounted at specific places. Therefore, the ceiling fan structure has very limited variations and decorations.

It is then the main theme of the invention to solve the above-mentioned problems.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a ceiling fan structure whose blade supports are installed on a decorative cover that is connected to a motor. The motor rotates the decorative cover, which then drives the blade supports to rotate. Therefore, the blade supports can be installed at any arbitrary places on the decorative cover according to one's need, rendering high versatility of the ceiling fan.

To achieve the above-mentioned objective, the disclosed ceiling fan structure includes a motor, a decorative cover, and several blade components. The decorative cover covers on the outer side of the motor, and is installed on the motor. Each of the blade components includes a support and a blade. Each blade is installed on a corresponding support. Each support is installed on the decorative cover. As the motor drives the decorative cover to rotate, thereby rotating the blade components.

The bottom of the motor is mounted with a connecting base that has a lamp. The bottom of the decorative cover has an opening for the connecting base to go through.

The bottom of the decorative cover has several fixing holes. The top of each support has a fixing part. Each support is mounted under the decorative cover, with a fixing element going downward through the corresponding fixing hole of the decorative cover and fixing onto the corresponding fixing part of the support. The supports are thus integrated to the decorative cover.

BRIEF DESCRIPTION OF THE DRAWINGS

These and other features, aspects and advantages of the invention will become apparent by reference to the following description and accompanying drawings which are given by way of illustration only, and thus are not limitative of the invention, and wherein:

FIG. 1 is an exploded view of the invention;

FIG. 2 is a partial cross-sectional view of the invention after assembly; and

FIG. 3 is an exploded view of a conventional ceiling fan structure.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Please refer to FIGS. 1 and 2 for the ceiling fan structure according to the invention. The disclosed ceiling fan structure includes a motor 1, a decorative cover 2, and several blade components 3 (only one of which is shown). The motor 1 is an external rotor motor. That is, the rotor surrounds a stator on the axis and rotates with respect to the axis. The decorative cover 2 encloses the motor 1 from the outer side thereof and is mounted on the rotor of the motor 1. In this embodiment, the decorative cover 2 is locked onto the rotor of the motor 1 using fixing screws 21. As the motor 1 rotates, the decorative cover 2 is driven to rotate as well.

Each of the blade components 3 includes a support 31 and a blade 32. Each of the blades 32 is installed on a corresponding support 31. Each support is installed on the decorative cover 2. In this embodiment, the bottom of the decorative cover 2 has several fixing holes 22. The top of each support 31 has a fixing part 311. Each support 31 is installed under the decorative cover 2. A fixing element 33 going downward through the corresponding fixing hole 22 of the decorative cover 2 and fixing onto the corresponding fixing part 311 of the support 31, thereby integrating the supports 31 and the decorative cover 2 together. When the motor 1 rotates the decorative cover 2, the blade components 3 are driven to rotate as well.

As described above, the invention has the advantage that the rotation of the blade components 3 is achieved via the decorative cover 2. Therefore, each of the blade components 3 can be installed on an arbitrary position on the decorative cover 2 and still achieve the desired rotation effect. Furthermore, the decorative cover 2 can be designed to have creative, characteristic style and shape. Each of the blade components 3 can be installed at an appropriate position on the decorative cover 2 under the consideration of practical and beauty purposes. Therefore, there are more places for the blade components 3 to install. The ceiling fan thus has higher versatility in shape and becomes decorative.

Besides, the bottom of the motor 1 is provided with a connecting base 11 for the connection of a lamp 4. The bottom of the decorative cover 2 has a corresponding opening 23 for the connecting base 11 to go through. In this case, the disclosed ceiling fan has the functions of both illumination and decoration.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to people skilled in the art. Therefore, it is contemplated that the appended claims will cover all modifications that fall within the true scope of the invention. 

What is claimed is:
 1. A ceiling fan structure, comprising a motor, a decorative cover, and a plurality of blade components; wherein the decorative cover encloses the motor from the outer side thereof and is installed on the motor, each of the blade components includes a support and a blade, each of the blades is installed on a corresponding support, and each support is installed on the decorative cover, so that the decorative cover is driven to rotate and the blade components are brought by the decorative cover to rotate.
 2. The ceiling fan structure of claim 1, wherein the bottom of the motor is provided with a connecting base for the connection of a lamp, and the bottom of the decorative cover has a corresponding opening for the connecting base to go through.
